1. 项目背景
唉!本文写起来都是泪点。不是刻意写的本文,主要是对日常用到的文件上传做了一个汇总总结,同时希望可以给用到的小伙伴带来一点帮助吧。
-
上传本地,这个就不水了,基本做技术的都用到过吧;
-
阿里云OSS,阿里云是业界巨鳄了吧,用到的人肯定不少吧,不过博主好久不用了,简单记录下;
-
华为云OBS,工作需要,也简单记录下吧;
-
七牛云,个人网站最开始使用的图床,目的是为了白嫖10G文件存储。后来网站了升级了https域名,七牛云免费只支持http,https域名加速是收费的。https域名的网站在谷歌上请求图片时会强制升级为https。
-
又拍云,个人网站目前在用的图床,加入了又拍云联盟,网站底部挂链接,算是推广合作模式吧(对我这种不介意的来说就是白嫖)。速度还行,可以去我的网站看一下:笑小枫
还有腾讯云等等云,暂没用过,就先不整理了,使用都很简单,SDK文档很全,也很简单。
2. 上传思路
分为两点来说。本文的精华也都在这里了,统一思想。
2.1 前端调用上传文件
前端上传的话,应该是我们常用的吧,通过@RequestParam(value = "file") MultipartFile file
接收,然后转为InputStream
or byte[]
or File
,然后调用上传就可以了,核心也就在这,很简单的,尤其上传到云服务器,装载好配置后,直接调用SDK接口即可。
2.2 通过url地址上传网络文件
通过url上传应该很少用到吧,使用场景呢,例如爬取文章的时候,把网络图片上传到自己的图床;图片库根据url地址迁移。
说到这,突然想起了一个问题,大家写文章的时候,图片上传到图床后在文章内是怎么保存的呢?是全路径还是怎么保存的?如果加速域名换了,或者换图床地址了,需要怎么迁移。希望有经验的大佬可以留言指导!
3. 上传到本地
这个比较简单啦,贴下核心代码吧
- 在yml配置下上传路径
file:
local:
maxFileSize: 10485760
imageFilePath: D:/test/image/
docFilePath: D:/test/file/
- 创建配置类,读取配置文件的参数
package com.maple.upload.properties;
import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
/**
* 上传本地配置
*
* @author 笑小枫
* @date 2022/7/22
* @see <a href="https://www.xiaoxiaofeng.com">https://www.xiaoxiaofeng.com</a>
*/
@Data
@Configuration
public class LocalFileProperties {
// ---------------本地文件配置 start------------------
/**
* 图片存储路径
*/
@Value("${file.local.imageFilePath}")
private String imageFilePath;
/**
* 文档存储路径
*/
@Value("${file.local.docFilePath}")
private String docFilePath;
/**
* 文件限制大小
*/
@Value("${file.local.maxFileSize}")
private long maxFileSize;
// --------------本地文件配置 end-------------------
}
- 创建上传下载工具类

}
访问图片的话,可以通过重写WebMvcConfigurer
的addResourceHandlers
方法来实现。
通过请求/local/images/**
将链接虚拟映射到我们配置的localFileProperties.getImageFilePath()
下,文件访问同理。
详细代码如下
package com.maple.upload.config;
import com.maple.upload.properties.LocalFileProperties;
import lombok.AllArgsConstructor;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
/**
* @author 笑小枫 <https://www.xiaoxiaofeng.com/>
* @date 2024/1/10
*/
@Configuration
@AllArgsConstructor
public class LocalFileConfig implements WebMvcConfigurer {
private final LocalFileProperties localFileProperties;
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
// 重写方法
// 修改tomcat 虚拟映射
// 定义图片存放路径
registry.addResourceHandler("/local/images/**").
addResourceLocations("file:" + localFileProperties.getImageFilePath());
//定义文档存放路径
registry.addResourceHandler("/local/doc/**").
addResourceLocations("file:" + localFileProperties.getDocFilePath());
}
}
- controller调用代码
package com.maple.upload.controller;
import com.maple.upload.util.LocalFileUtil;
import lombok.AllArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;
import javax.servlet.http.HttpServletResponse;
import java.util.List;
import java.util.Map;
/**

*/
@Slf4j
@RestController
@AllArgsConstructor
@RequestMapping("/local")
public class LocalFileController {
private final LocalFileUtil fileUtil;
/**

*/
@PostMapping("/uploadImage")
public String uploadImage(@RequestParam(value = "file") MultipartFile file) {
if (file.isEmpty()) {
throw new RuntimeException("图片内容为空,上传失败!");
}
return fileUtil.uploadImage(file);
}
/**

*/
@PostMapping("/uploadFiles")
public List<Map<String, Object>> uploadFiles(@RequestParam(value = "file") MultipartFile[] files) {
return fileUtil.uploadFiles(files);
}

public void download(@PathVariable("fileName") String fileName, HttpServletResponse response) {
try {
fileUtil.downLoadFile(response, fileName);
} catch (Exception e) {
log.error("文件下载失败", e);
}
}
}
调用上传图片的接口,可以看到图片已经上传成功。
通过请求/local/images/**
将链接虚拟映射我们图片上。
批量上传,删除等操作就不一一演示截图了,代码已贴,因为是先写的demo,后写的文章,获取代码片贴的有遗漏,如有遗漏,可以去文章底部查看源码地址。
